Tina Fey
While her alter ego, Liz Lemon, would never be caught dead in a red carpet gown (she did just get married in a Princess Leia costume, after all), this funny lady is no dummy when it comes to stepping up her fashion game at award shows. She stunned in a maroon Vivienne Westwood dress in her preferred silhouette—strapless and floor-length—at the 2012 Emmy Awards. She's also been known to favor Oscar de la Renta at major events and to shake things up with a mermaid tail.
Julianne Moore
The radiant redhead's neon yellow Dior dress at the 2012 Emmy Awards was an eye-catching deviation from the black and white ensembles she tends to prefer when walking the red carpet.
Jennifer Lawrence
As the new face of Miss Dior, the Silver Linings Playbook actress definitely has a preference for the French designer label. She chose a dramatic Dior couture gown with a full skirt for the premiere of her film at the Toronto Film Festival.
Claire Danes
The Homeland star popped at the 2012 Emmy Awards in a bright yellow Lanvin gown, which she had altered to fit her tiny baby bump. This year saw the actress reaching for J. Mendel gowns for two red carpet biggies: the Golden Globes and the Met Gala.
Nicole Kidman
This red carpet veteran loves walking the red carpet in L'Wren Scott, but she opted for a white Antonio Berardu gown decorated with blue sequins for the 2012 Emmy Awards.
Sofia Vergara
The Modern Family star is known for showing off her figure in form-fitting floor-length gowns, often with a mermaid tail to balance out her curves. A keyhole cutout upped the va-va-voom factor of her teal Zuhair Murad halter dress—a deviation from her go-to strapless gowns—at the 2012 Emmys.
Naomi Watts
The blonde beauty has taken bold fashion risks during her recent promotion of The Impossible, wearing a white Marchesa cocktail dress with puffy sleeves at the Madrid premiere and a Tom Ford LBD with billowing sleeves that attached to the dress' skirt in London. But the amazing Aussie also knows how to nail more traditional looks, like this floral Zac Posen gown that she wears with retro glam pin curls.
Anne Hathaway
The Les Misérables star turned heads in a goth glam Tom Ford dress and gladiator sandals at the New York premiere of her film. She's been known to turn up the va-va-voom volume in Valentino gowns and the occasional Armani Privé number.
Marion Cotillard
If this French beauty is hitting the red carpet, chances are she's doing it dressed in Dior. As the face of the fashion house, she has stepped out in various Dior dresses, including this navy couture number with a textured skirt that she wore to the Gotham Film Awards.
Jessica Chastain
We've seen the redheaded beauty in more than one Jason Wu cocktail dress this year, but it was her yellow Stella McCartney number at the Heiress Broadway Revival event that stood out as one of her more memorable red carpet moments.
